To all-whom it may concern:

Be it known that we, MAX Gonnnn and BERTHOLD EIINER, subjects of-the German Emperor, residing, respectively, in Berlin and in Reinickendorf-Vest, near Berlin, in the Kingdom of Prussia, Germany, have invented certain new and useful Improve ments in'Antifriction-Bearings, of which thefollowing is a full, clear, and exact description.

Our invention relates to anti-friction bearings, and more particularly to that class thereof wherein the outer casing member has a convex contour and is located and fits closely in an external casing or ring having a corresponding concavely-formed inner surface.

In ordinary practice, the corresponding concave and convex contours are spherical, and this construction and arrangement are sometimes employed for the purpose of per:

mitting angular variations and adjustments between the parts, as where a shaft or axle is shifted angularly with reference to the supporting means during operation. It is also valuable and advantageous for other reasons. Thus, for instance, the external casing ring may serve as a strengthening or reinforcing means for the outer casing member of the hearing, or may serve to connect and hold the latter together when it is made in a plurality of parts or sections. Again, the external casing ring maybe formed with a cylindrical outer surface which adapts it to'be inserted into the general and ordinary housing provided .or such purpose, and this irrespective of the peculiar or unusual shape given to the outer member of the bearing. Several different methods of introducing such aconvex bearing into the concave casing have been used. For instance, the outer cap or casing is sometimes'formed in a plurality of sections to permit of assemblage, but obviously the casing is weakened thereby, and it is disadvantageous in other particulars. Another method of obtaining the same result is to form recesses in the edge or edges of the casing or cap of sufficient size to permit the introduction of the bearing into the casing transversely thereto, after which the hearing may be turned pivotally Within the casing until its outer spherical contour corresponds with and is contained within the spherically-formed inner surface of the casing.

It is the object of our present invention to obtain all of the advantages involved in the use of such a combined bearing and -mounting, and to this end we form the eX- ternal casing ring with continuous and uninterrupted edges at the sides of its concave surface, and rely on the elasticity of the parts to permit of assemblage and disassemblage by deformation.

More specifically, the bearing is introduced into the external ring transversely thereto, after which it is turned pivotally until it is properly seated therein. It will be obvious that thistransverse introduction of the bearing into the ring permits the elasticity of the latter to be availed of to its fullest extent, for-the reason that only a portion 'of the outer bearing member is thus brought into contact with the external ring, and thereby the latter may be readily deformed and elongated to an extent sufficient for the purpose.

We have shown in the accompanying drawing and described in the specification a preferred form of bearing and casing embod'ying the principles of our invention, but obviously many changes and variations may be made therein without departure from its spirit; and, generally speaking, we do not desire to limit ourselves to any specific forms except in so far as such limitations are speci-'.

wherein the outer casing member of the bearing is constructed in two sections.

The anti-friction hearing may be of any desired or suitable construction and in itself forms no part of the invention. As shown in Fig. -1, it comprises an inner casing member b, an outer casing member a, and two' series of rolling elements or balls 0 and d mounted between the casing members. The outer casing member a has a 'sphericallyformed outer surface, which corresponds to the spherically-formed inner surface of the cap or casinge, wherein it is mounted, the ring 6 being constructed of suitable elastic or deformable material for the purpose subsequently to be set forth, and having subthe bearing is preferably introduced transversely or laterally, for instance at right angles, into the outer casing ring 6, which operation as before described causes the distortion of the elastic and deformable ring e, it being thereby elongated in the manner previously referred to. After the bearing is thus partially introduced it is turned pivotally with reference to the casing ring 6 until the outer spherical surface of the hearing and the inner spherical surface of the casing correspond, in themanner well understood in the art.

I11 Fig. 2, we have shown a modified form of our invention, wherein the outer casing member of the bearing is constructed of two separable sections a1, a2. In this instance, the bearing is assembled, and the two sections a-l, a-2 thereby brought to properposition, after which the bearing as a whole is inserted within thev external casing ring in the manner before described. It will be seen that in this case the external casing ring serves the additional function of holding the sections of the bearing member together, as well as of strengthening the hearing as a Whole. It is also to be noted that in both figures the external ring is formed'with an outer cylindrical surface, thus adapting it to be inserted in the customary and ordinary housings provided for that purpose.

The parts may be assembled in the manner specified with the minimum of force and distortion, and when assembled, they meet all the requirments of commercial use and practice.

As previouslystated,inany variations and equivalents will suggest themselves to those skilledin the art without departure from our invention. In the specific description above, we have referred particularly to the elasticity and deformation of the external casing, but obviously similar capabilities and results would be secured, if the outer member of the bearing were sufficiently elastic. In other words the assemblage or disassemblage may be accomplished by the de formation of either or both of these parts.

Further, this'means for permitting or facilitating assemblage may be applied-1n other constructions and is not limited simply to its use with anti-friction bearings, as it might be similarly employed Whenever it is desired to introduce a member, formed with a convex contour, within an external casing having a corresponding concavelyformed inner surface.

Having thus described our invention, its construction and mode of operation, what we claim and desire to secure by Letters Patent of the United States is as follows:

1. The combination of an anti friction bearing having a convexlyformed outer surface with an external casing ring therefor having a corresponding concavelyformed inner surface, the said external ring having substantially continuous and 1ininterruptecl edges at the sides of its concavelyformed surface, and one or both of the parts being sufficiently elastic to permit of assemblage and disassemblage by deformation.

The combination of an anti friction bearing having a convexlyformed outer surface with an external casing ring therefor having a corresponding concavelyformed inner surface, the said external ring having substantially continuous and uninterrupted edges at the sides of its concavelyformed surface, and one or both of the parts being sufficiently elastic to permit of the insertion and removal of the bearing transversely thereto.

3. The combination of an antifriction bearing having a convexly-formed outer surface with an external casing ring therefor having a corresponding concavelyformed inner surface, the said external ring having substantially continuous and uninterruptededges at the sidesof its concavelyformed surface, and one or both of the parts being sufliciently elastic to permit of assemblage and disassemblage by deformation, and the external casing ring being formed with a cylindrical outer surface.

In witness whereof, we have hereunto signed our names in the presence of two subscribing witnesses.
